Again, this can be broadcast to all devices, an update of just one category of device, or to an individual device. You can set policies in the rConfig system and use the Configuration Compliance Manager to check that all the configurations on your network comply with those specifications. This means that the tool is only suitable for small networks and not those that are managed by a team. Net LineDancer , which is also known as NetLD , is not free to use, but you can try it on a day free trial.
Net LineDancer has all of the features that you need from a configuration manager. It automatically logs all devices and takes a snapshot of their configurations to establish a stored baseline.
Subsequent configuration sweeps can identify changes to each device. Those comparisons can also be made on-demand. The stored configuration files can be re-loaded onto equipment in bulk, by device type, or individually. The software can manage thousands of devices and the monitoring processes can be automated through the tool. Reporting features of the tool log the users that make changes to the settings of devices.
Net LineDancer and Net StreetDancer cover all of the essential functionality that you need from a configuration manager. This newly-revamped package is worth a look if you are in the market for a configuration manager. BMC has done a very nice job with its new configuration system because it has paid attention to the standard requirements with which many data-driven businesses have to comply in order to win contracts and keep to service level agreements SLAs.
If you are contractually or legally bound to enforce one of these standards, you will be greatly aided in your duties by TrueSight Network Automation. Not only does the system list the settings that network devices need in order to comply with a given standard, it enforces those requirements. This method will save you a lot of time reading through standards documents and trying to work out how to translate the requirements into device settings. The system starts off by scanning the system , logging all devices, checking for compliance requirements, and adjusting device settings.
After that, the monitor will back up all configurations. TrueSight will continue to scan and prevent any changes or alert you when they happen. You can restore standard configurations manually, but the automated option of TrueSight will perform that task for you.
The console of TrueSight Network Automation can be allocated in sections to different user groups. This will allow you to make different dashboards available for different team members.
Changes to configurations and updates to firmware can be rolled out in bulk. The system will detect new patches and updates and alert you to them; these will then be installed automatically on all relevant devices with your approval. This optional extra will scan for security threats and block them. It also keeps in touch with vendor sources and the NIST National Vulnerability Database to detect security weaknesses and alert you to the need to patch the system when a relevant solution is made available.
This vulnerability monitoring applies to servers as well as to network devices. You have to pay for this network configuration software.
Device42 is an impressive combination of infrastructure management modules. The tool includes IT asset management , IP network address management , data center infrastructure management , and configuration management.
If you operate a data center whether for in-house services or as an external provider, you should pay attention to this configuration management option. The accompanying functions of this tool make it extremely interesting for data centers. The Device42 system is available for on-premises installation or as a cloud-based service.
Installation begins by logging an inventory of your equipment and backing up the configurations of each. The monitor sweeps the network continuously to look out for changes in the settings of your network devices. The tracker not only logs all device settings, it records the firmware versions of each. It also covers the operating systems of your servers and all of the applications and software loaded onto them.
The Device42 facilities are all locked off by authentication procedures. You can add new accounts for individual team members, so this tool would be great for middle-sized and large networks that are team-supported.
Device42 is paid for by a subscription. There are three plan levels for the tool, and fortunately, the configuration management module is included in the Core plan , which is the cheapest version of the software. You can get a look at the system with a free online demo. If you want to go ahead and buy the system, you get a day trial period , so you can back out in the first month and get all of your money back.
The software can be installed on Windows , Mac OS and you can get it on Linux computers through a virtual environment. You can also integrate the service with Azure , and AWS online services.
The Configuration Center from Lan-Secure has a no-frills interface, but it delivers a competent configuration management service. The tool has all of the essential capabilities that you need to control the settings of your network devices. The Configuration Center will scan your system to register all of your network devices and then make backups of their settings.
The network management software is able to manage a multi-vendor environment and will enable you to update the settings of all devices, specific device types, or individual devices. The Configuration Center software will periodically check the settings of each device and compare them to the configuration backups it holds in storage. Depending on how you set up the system, the detection of an unauthorized configuration change will either prompt an alert or an automatic rollback to the approved settings held in the backup for that device.
Alerts can be sent by email to a team member who has been allocated responsibility. The tool can manage remote sites as well as the center where all of your configuration backups are stored.
Inter-site communications are covered by SSH security. The software can be installed on Windows. You have to pay for the Configuration Center , but it is very reasonably priced. You can get a day free trial of the system to assess it before you buy. You will find some very comprehensive systems in this list and some worthy contenders that cost little to no money. When you select a configuration management system for your network, you will need to consider the system requirements , particularly the operating systems that the software can run on in order to narrow down your choices.
The size of your network and the availability of funds will be other important considerations that will guide you towards the right NCM tool for your company. The ability to try out a system on a free trial or the offer of a money-back guarantee should help you narrow down your assessment. If you can try before you buy without obligation, you will be more confident to install software.
Otherwise, you might discover too late that it is difficult to use or inappropriate for your configuration management needs. The field of cybersecurity is becoming very hot right now. Sometimes, firewalls, attack protection services, and intruder detection systems fail. Your second line of defense lies in the control over the settings of your network devices and a policy to keep all firmware and operating systems up-to-date with the latest system updates and patches.
So, even if you run the network for a small company, there are no excuses for not implementing configuration management and change control on your network. Have you implemented a configuration management system for your network? Which manager did you choose, and why?
Leave a message in the Comments section below to share your experiences with the rest of the community. Network configuration management involves standardizing the settings of network devices, such as switches, routers, and firewalls to make intrusion more difficult.
One tactic that some hackers use to aid their undetected exploration of the network is to alter certain settings on switches. The security aspect of network configuration management requires that any unauthorized changes get rolled back immediately. There are many different aspects to look out for in network configuration. Visit the management console of each switch, check on IP address allocation through an IP address manager, and check on the port statuses of all devices connected to the network.
This is a mundane and time-consuming activity that specialist software can achieve more effectively than manual procedures. This site uses Akismet to reduce spam.

To enable all Defender for Cloud features including threat protection capabilities, you must enable enhanced security features on the subscription containing the applicable workloads.
Enabling it at the workspace level doesn't enable just-in-time VM access, adaptive application controls, and network detections for Azure resources. You'll notice that each Microsoft Defender plan is priced separately and can be individually set to on or off. For example, you might want to turn off Defender for App Service on subscriptions that don't have an associated Azure App Service plan. From the Select subscriptions and workspaces to protect with Microsoft Defender for Cloud list, select the subscriptions and workspaces to upgrade and select Upgrade to enable all Microsoft Defender for Cloud security features.
If you need to disable enhanced security features for a subscription, the procedure is the same but you select Enhanced security off :. After you disable enhanced security features - whether you disable a single plan or all plans at once - data collection may continue for a short period of time. As many Java-based applications can leverage Log4j 2 directly or indirectly, organizations should contact application vendors or ensure their Java applications are running the latest up-to-date version.
Developers using Log4j 2 should ensure that they are incorporating the latest version of Log4j into their applications as soon as possible to protect users and organizations. The vulnerabilities allow remote code execution by an unauthenticated attacker to gain complete access to a target system. It can be triggered when a specially crafted string is parsed and processed by the vulnerable Log4j 2 component. This could happen through any user provided input.
Successful exploitation allows for arbitrary code execution in the targeted application. Attackers do not need prior access to the system to log the string and can remotely cause the logging event by using commands like curl against a target system to log the malicious string in the application log. When processing the log, the vulnerable system reads the string and executes it, which in current attacks is used to execute the code from the malicious domain.
Doing so can grant the attacker full access and control of the affected application. Given the fact that logging code and functionalities in applications and services are typically designed to process a variety of external input data coming from upper layers and from many possible vectors, the biggest risk factor of these vulnerabilities is predicting whether an application has a viable attack vector path that will allow the malformed exploit string to reach the vulnerable Log4j 2 code and trigger the attack.
A common pattern of exploitation risk, for example, is a web application with code designed to process usernames, referrer, or user-agent strings in logs. These strings are provided as external input e. An attacker can send a malformed username or set user-agent with the crafted exploit string hoping that this external input will be processed at some point by the vulnerable Log4j 2 code and trigger code execution.
Figure 1. CVE and CE exploit vectors and attack chain. After further analysis of our services and products, below are a few mitigation strategies given by various Microsoft services. The mitigation based on disabling message lookup functionality — through enabling the system property log4j2.
Customers should still apply the latest security updates or apply other documented mitigation steps such as the removal of the JndiLookup. Microsoft recommends that all Customers upgrade to December release which has updated the Log4J library to 2. Azure Arc-enabled data services us Elasticsearch version 7. However, your applications may use Log4J and be susceptible to these vulnerabilities. If you are not able to re-package your application with a newer version of Log4j and you are using Log4j versions 2.
Note that this command will also restart your App Service hosted application. In our investigation so far, we have not found any evidence that these services are vulnerable however customer applications running behind these services might be vulnerable to this exploit. We highly recommend customers to follow mitigations and workarounds mentioned in this blog to protect their applications. Additional guidance for Azure WAF is located here.
Your instance may be vulnerable if you have installed an affected version of Log4j or have installed services that transitively depend on an affected version. For more information on checking for vulnerable Log4j 2 instances installed, please see the following Microsoft Document: Verify the version of Log4j on your cluster. Customers are recommended to apply the latest Log4j security updates and re-deploy applications. If you are not able to and you are using Log4j versions 2. Note that these application settings will restart your Function apps, and it will no longer use warm workers which will impact future cold-start performance.
All Azure HDInsight 5. Any HDI 4. For new clusters created using HDI 4. Jobs should only be executed after the patch has been applied and the impacted nodes have been rebooted to ensure that the vulnerability has been fixed. The patch should be run on each new cluster as a persisted script action until a new HDInsight image is available that incorporates the patch. Applications deployed to Azure Spring Cloud may use Log4j and be susceptible to this vulnerability.
